SPECIFICATION forming part of Letters Patent No. 388,209, dated August 21, 1888.

Application filed Mayfll, 1888. Serial No. 275,615. (No model.)

To all whom it may concern:

Be it known that I, Gnouon C. LOGAN, of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Station-Indicator, of which the following is a full, clear, and exact description.

My invention relates to an improvement in stationindicators, and has for its object to provide a means whereby an approaching station may be indicated within a car, and wherein the apparatus containing the names of the several stations may be operated from the engine or car; and the further object of the invention is to provide a device of simple and durable construction which may be readily manipulated and not liable to disarrangement.

'The invention consists in the construction and combination of the several parts, as will be hereinafter set forth, and pointed out in the claims.

leferencc is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the device with the front plate removed. Fig. 2 is a transverse vertical section on line no a of Fig. 1. Fig. 3 is a vertical section of the air-cylinder and piston. Fig. 4- is a side elevation of the triprod block and aetuatingpawl. Fig. 5 is a plan view of the same. Fig. 6 is a side elevation ofthe drnnrretaining latch, and Fig. 7 is a plan View of the same.

In carrying out the invention, a box or casing, 10, preferably rectangular in contour, is attached to the wall of a car in such position as to be most readily seen by the greatest number of passengers. The front 11 of the casing 10 is provided above the center with a transverse opening, 12,which opening is ordinarily closed by a glass or other transparent plate, 13, as best shown in Fig. 2. The said front of the casing may be permanently fixed to the sides and ends, or be hinged thereto to form a door, as desired.

\Vithin the casing 10 vertical brackets 11 are attached, preferably, to the top or back,which brackets extend downward from the top near each. side of the casing to within a suitable distance of the bottom, as is best shown in Fig. 1. Near the upper end of the casing a drum, 15, is pivoted in the said brackets 14, which drum is preferably octagonal in crosssection and provided longitudinally at the several angles upon the periphery with a series v of lugs or projections, 16. The said drum is further provided at the ends with disks 17, which disks are adapted to carry upon their outer faces a series of horizontally-projecting pins, 18, one pin being preferably affixed to the disk in alignment with each angle of the drum.

The drum 15 is adapted to carry an endless apron, 19, which apron consists of a series of boards, 20, constructed of card-board or equivalent light material, the several boards being of a length slightly less than the distance between the disks of the drum and of a width nearly equal to theseveral faces of the same. In forming the apron the boards are united by a series of links, 21, as best shown in Figs. 1 and 2; but these links may be substituted by other equivalent devices. Owingto this construction, as the drum 15 revolves, the boards lie fiat upon the face of the said drum, permitting the projections 16 to intervene the several boards and retain the same as they fall upon, the drum in their proper position, as is also best illustrated in Fig. 1.

In the base of the casing at one side a cylinder, 21, is located having an open top, which cylinder communicates with an air-cylinder, 22, located beneath the engine or beneath the several cars, as may in practice be found most desirable. \Vithin the cylinder 21 a piston, 23, is held to reciprocate. The rodstem 21 thereof is tubular and projects upward through an arm, 25, integral with one of the brackets 14, as best shown in Fig. 2. The tubular stem is surrounded by a spiral spring, 26, which spring has a bearing upon the collar 33, attached to the pistoirrod at one end and against the bracket-arm at the upper end. The lower end of the pistonhead at the center is provided with an aperture, in which aperture a valve, 27, is held, the said valve being provided with a rod, 2S,extending upward through the tubular piston-rod above the top thereof, the rod 28 terminating at the upper end in a button,29, being guided through the medium of springs 30, attached to said button and extending downward within the piston-rod to bear against the inner side thereof, as best illustrated in Fig. 3.

Above the bracket-arm a second arm, 31, is secured,whieh arm is adapted to receive the button 29 as the piston ascends and limit the motion of the rod 28 and likewise the movement of the piston. From an arm, 33, extending from the collar 33, fast on the pistonrod above the pistouhead, a trip'rod, 32, is projected upward through the top of the easing at one side of the drum. Upon the triprod 32 a block, 34, is secured, upon which block a pawl, 35, is pivoted, the said pawl being held in a horizontal position at right angles to the block by a spring, 36, secured at one end of the block 34, the other end of the said spring being held in a slot formed in the face of the pawl, as best shown in Fig. 4.

The upper surface of the pawl is fiat and adapted for engagement with the several pins 18 of the disk. The pawl 35 is free to move upward, but is prevented from moving downward beyond its normal position by an offset, 37, formed in the upper face of the pawl,which recess is adapted to engage a face of the block 34, as best shown in Fig. 5, or other equivalent means may be substituted.

A second block, 38, is secured to the back of the casing above the block 34, upon which block a latch, 39, is pivoted, the said latch being normally held in a horizontal position over the pins of the drum through the medium of a spring, 40, secured to said latch and block in a similar manner as the spring 36 of the pawl.

The latch 39 consists of an arm provided with hook-like head 41, as best shown in Figs. 6 and 7. The head 41 of the latch is adapted to engage the several pins 18 of the drum, being free to move upward, but normally re taincd in a horizontal position in engagement with the pin through the medium of the afore said spring 40.

Over the casing 10 a suitable gong, 42, is attached to the car-body within the same, the trip-lever of which gong is connected by a chain, 43, with a bell-crank, 45, pivoted upon a suitable standard attached to the upper end of the casing. The bell-crank 45 is actuated by engagement with the head 46 of the triprod 32, as best illustrated in Fig. 1. Thus, in operation, when the air is admitted below the piston 23 the said piston is elevated, which movement also elevates the trip-rod 32, whereupon the pawl 35 engages the nearest pin 18, carrying the pin above the one in contact to an engagement with the hooked end of the latch 39, which latch, being forced upward as the drum revolves, is thereupon brought down to a bearing upon the pin through the medium of the spring 40. This having been accomplished, the button 29 of the piston, which is normally elevated above the piston-rod, is brought in contact with the arm 31, whereupon the valve 27 is opened andthe air permitted to escape through diagonal ports 47 in the piston-head out through the cylinder 21, as best shown in Fig. 2, whercupon the said head is permitted to resume its normal position. It will thus be observed that at every elevation of the piston the pins of the disk are made to change position, causing one of the boards at each time to register with the opening 12 in the casing. \Vhen the trip-bar 32 is elevated, the head 46 will act upon the bcllcrank 45, and ring the gong 42 simultaneously with the appearance of the new board before the opening12 in the casing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a station-indicator, the combination, with a drum and an endless indicating-belt carried by said drum, of an air-cylinder below the drum, a piston reciprocating in said cylinder, a trip-rod connected to the piston, a pawl on the trip-rod for engaging the drum to rotate the same, and a latch on the said trip-rod and engaging the drum to lock it in position, substantially as described.
